he said he'd have one with everything, in most european country, hot dogs are sold with no toppings, so, if u buy a hot dog, all u can get is a sausage in a bun, then you have to add topings on to the hot dogs by yourself, and there are more than 20 toppings, e.g ketchup, Mustard, Chips, pickel, etc, so the person you mention above likes hot dogs with every possible topping they offer, it also show how greedy that person is. hope that helps :)
